The energy used is radiant energy.
That is related to the Law of Conservation of Energy. To boil water, you need to get it hotter, that requires energy, and this energy has to come from somewhere.

When burned, oil (or most other types of fuel) release heat energy. This heat energy can be used to boil water. The now water vapor can be used to turn a generator which can turn kinetic energy (from the water vapor moving the fan blades) to electrical energy by using a coiled wire and a magnetic field.
Nuclear energy is not collected, it is released and used. Most often the use is to boil water for a steam generator of electricity.
The primary energy source used to boil water is thermal energy. This can come from various sources such as gas, electricity, or fire. The thermal energy raises the temperature of the water to its boiling point, changing it from liquid to vapor.

The type of energy which is used to boil water is commonly heat energy. This will result to a changes from the liquid state to gaseous in form of water vapor,.
That is related to the Law of Conservation of Energy. To boil water, you need to get it hotter, that requires energy, and this energy has to come from somewhere.
yes because burning is a chemical process that is used to boil water with heat
yes, that's what you do when you use gas or wood to boil water
Boiling Water OBV!
Heat. Which is used to boil water which turns a turbine. The turbine generates electricity.
It depends on the battery and the size of the kettle. It also depends on the starting temperature of the water and the air pressure, if you are at higher altitude or lower air pressure it takes less energy to boil the water, and also if the water starts at a higher temperature it takes less energy to boil. Definitely some batteries have enough energy. You'd have to calculate the amount of energy required to boil the water and look at the amp hour measurement on the battery, that tells you the total energy stored in the battery.

Yes, that is how they are used to generate electricity.
